...I can't understand how to translate this.
Okay, it's time to update the fucking instructions file.
Download SetupReiPatcherAndAutoTranslator.rar file and _AutoGeneratedTranslations.txt. Optionally, take the /Sprites folder and Deck List.txt.
Unzip the Autotranslator with WinRar (It's *free* if you keep closing its requests to buy it) and place the .exe inside in the game's main folder, next to the game's .exe.
Run the Setup.exe, allow it to finish, then press any key to close the console. It will create a new folder and a new .exe.
Run the game with the new .exe at least once. It will also create a new folder. Close the game afterwards.
Place _AutoGeneratedTranslations.txt in AutoTranslator/Translation/en/Text, overwriting the current (Nigh-empty) file. Optionally, place the /sprites folder in the UserCustomData folder, though overwriting is not nessesary for that.
Start up the game using either .exe, I recommend the original one going forwards. The game is now fully-translated and optionally has a full set of card skins.
If you took the deck list, the way you import these decks is to CTRL+C the long codes beneath the descriptions, then from the 'Edit Deck' screen, click 'Create new from deck code (Clipboard).' This will import the copied deck, sadly without its colors.
